4Pcs Ad620 Microvolt/Millivolts Voltage Amplifier Signal Instrumentation Module Board
Description:
Using Ad620 As The Main Amplifier, Can Amplify Microvolt/Millivolts Voltage. Magnification 1.5-10000 Magnification, Adjustable. High Precision, Low Offset, Better Linearity. Adjustable Zero To Improve Accuracy. Can Be Used For Ac, Dc Signal Amplification. (Module Use, Need To Have A Certain Electronic Basis, If No Basis Customers, Please Carefully Purchase.)
Product Highlights:
1: Wide Supply Voltage Range, The Ad620 Amplification Of This Product Can Be Amplified Microvolts, Millivolt, Compared To Lm358 Amplification Accuracy, Better Linearity, The Maximum Voltage Output Range Of ± 10V.
2: Magnification Range, Magnification Up To 1000 Times, Only Through A Potentiometer Can Be Adjusted.
3: Adjustable Zero Through The Zero Potentiometer To Adjust The Zero, Improve Accuracy, There Will Be No Zero Drift Phenomenon To Meet Customer Needs.
4: Negative Voltage Output, The Module Uses 7660A Chip Output Negative Voltage (-Vin), Can Be Provided To The Customer To Drive Other Dual Power Load.
5: Mini Type, The Size Of 32 * 22Mm, Evenly Distributed Around The Four 3Mm Positioning Holes, Both Sides Of The Port 2.54Mm Standard Pitch Pinhole.
